LKMS - A Legal Knowledge Management System Exploiting Semantic Web Technologies.
ABSTRACT Semantic Web, using formal languages to represent document content and providing facilities for aggregating information spread
around, can improve the functionalities provided nowadays by KM tools. This paper describes a Knowledge Management system,
targeted at lawyers, which has been enhanced using Semantic Web technologies. The system assists lawyers during their everyday
work, and allows them to manage their information and knowledge. A semantic layer has been added to the system, providing
capabilities that make system usage easier and much more powerful, adding new and advanced means for create, share and access

ABSTRACT: Web browsing involves two tasks: finding the right web page and then making sense of its content. So far, research has focused on supporting the task of finding web resources through ‘standard’ information retrieval mechanisms, or semantics-enhanced search. Much less attention has been paid to the second problem. In this paper we describe Magpie, a tool which supports the interpretation of web pages. Magpie offers complementary knowledge sources, which a reader can call upon to quickly gain access to any background knowledge relevant to a web resource. Magpie automatically associates an ontologybased semantic layer to web resources, allowing relevant services to be invoked within a standard web browser. Hence, Magpie may be seen as a step towards a semantic web browser. The functionality of Magpie is illustrated using examples of how it has been integrated with our lab’s web resources.01/2003;

ABSTRACT: Ontology-based approaches to Knowledge Management promise better access to relevant know-ledge by providing a domain-specific vocabulary that is used for describing the contents of knowledge as well as for retrieving that knowledge. Despite the potential benefits, ontology-based approaches require a considerable amount of commitment and expertise in tasks like creating and maintaining ontologies, annot-ating documents and integrating information. We are studying and implementing a methodology for auto-mating such tasks, which makes use of Information Extraction and Integration, Ontology Learning and Se-mantic Browsing to effectively acquire, share and reuse knowledge in an organizational setting. Applica-tions of the proposed methodology are under development for knowledge management in the legal domain and in the field of biotechnology.
Conference Proceeding: SEAL - A Framework for Developing SEmantic Web PortALs.[show abstract] [hide abstract]
ABSTRACT: The core idea of the Semantic Web is to make information accessible to human and software agents on a semantic basis. Hence, Web sites may feed directly from the Semantic Web exploiting the underlying structures for human and machine access. We have developed a domain-independent approach for developing semantic portals, viz. SEAL (SEmantic portAL), that exploits semantics for providing and accessing information at a portal as well as constructing and maintaining the portal. In this paper we focus on semantics-based means that make semantic Web sites accessible from the outside, i.e. semantics-based browsing, semantic querying, querying with semantic similarity, and machine access to semantic information. In particular, we focus on methods for acquiring and structuring community information as well as methods for sharing information.As a case study we refer to the AIFB portal - a place that is increasingly driven by Semantic Web technologies. We also discuss lessons learned from the ontology development of the AIFB portal..Advances in Databases, 18th British National Conference on Databases, BNCOD 18, Chilton, UK, July 9-11, 2001, Proceedings; 01/2001
